Calculate Attenuation Circuit ( L-Pad )


divider
Speaker impedance: Ohm
Wanted Attenuation: dB
Series resistance R1: Ohm
Parallel resistance R2: Ohm



 
Calculate here the attenuation and new driver-impedance of an existing attenuation circuit or with resistors different then calculated before.

Important:
Impedance from this circuit has to be as close as possible to the original driver impedance. If the difference is >0.25 ohm the filter function is deviating of the computations.


Enter R1, R2 and the driver impedance.
The impedance and attenuation of the circuit including the driver will be calculated.


This can be usefull if you have to use resistors with a different values then calculated for the attenuation circuit.

Driver impedance:  ohm
Series resistance R1  ohm
Parallel resistance R2  ohm
Driver impedance (incl. attenuator):   ohm
Attenuation:   dB
Driver impedance difference:   ohm
Message: 
 
The changed Driver impedance is important to calculate the Crossover Network!
